s unloading position in This cable 17 is used for raising and lowerard 4 and is adapted to pass upwardly over a pulley 18 at one side of the upper end of standard 4, then pass downwardly between the two standards and through a suitable opening in ring 7 The cable 17 then passes around the two spaced pulleys 19 at the bot tom of the inner member 6, thence upwardly through an opening in the ring 7 thence up? wardly over a pulley 18, carried by the member 4 directly opposite the pulley 18.

The end of the cable is attached to the upper end of the member 4 asshown at 19. From this structure, it willbe apparent that when the clutch member 20, which controls the connection between the gears 11 and 13 is actuated, the winding drum 16 is rotated in either direction for winding the cable 17 thereon or unwinding it thereover for rais ing or lowering the member 6.

The bevel gears 12 are adapted to mesh with the gear 21 which has co-operative connection with worm gear 22 driving stub shaft 23 and drum 24. The connection between gears 12 and 21 is controlled by means of the clutch 25.

From this structure, it will be apparent that when it is desired to move the car in close proximity to the platform 1, a cable hitch may be engaged with drum 24 and the drum rotated through actuation of clutch 25 for pulling the car toward the platform.

The upper end of the movable standard 6 is provided with a transverse platform member 26. This platform or table 26 supports spaced bearings 27 and 27'. Rota-table within these bearings is a tubular member 28 having one end closed by means of a plug 29 having an integral bracket 30 supporting one end of a shaft 31, the other end of said shaft being supported by means of a bracket 32 mounted upon the rotatable member 28 and movable therewith.

The end of the rotatable member 28, opposite the plug 29 is closed by means of the interior bearing member 33, it being understood that the plug 29 also forms a bearing for the centrally disposed shaft 34. The shaft 34 extends through the bearing member and has a clutch member 35 upon its outer end. This clutch member 35 co-operates with clutch member 36 of the extension shaft 37 for simultaneously rotating the two parts.

The shaft 37 is centrally disposed within the, movable tubular member 28' which has its ends closed by means of the bearing plugs 38 and 38'. The inner ends of the bearing plugs 33 and 38 are provided with interfittin g parts so that when they are disposed in alignment, as shown in Figure 3, these parts, which comprise the reduced sleeve 39and the tapered socket 39' will prevent lateral movement of the rotatable members 28 and 28.

Extending laterally from the bearing plug meaeev 33 are the brackets 40 formed with bearing parts 41 and extending through these bearing parts is a shaft 42 which also extends throughv the bearing member 43 on the plug bearing 38, the bearing 43 being disposed between bearing members 41 as shown in Figure 1 and rotatable with shaft 42.

The outer end of shaft 42 carries a worm gear 44, meshing with worm 45 on shaft 46. This shaft 46 carries a hand crank 47 whereby to manually impart movement to shaft 42 for adjusting the movable part 28 relative to the main part 28.

The outer end of shaft 37 is provided with spaced collars 48' and 48 and movable be tween these collars is a locking arm 49 which is adapted to move shaft 37 toward shaft 34 in order to engage the clutch members 35 and 36, but when the arm 49 is withdrawn from betwen the collars, the clutch members 35 and 36 may then be disengaged for shifting the part 28'.

It will be apparent from the foregoing that the sectional part 28 of the rotatable tubular member can be either positioned in alignment with the member 28, as shown in full lines in Figure 2, or may be quickly and easily positioned parallel with member 28, as shown by the dotted lines in Figure 2. When the member 28 is moved to the dotted line position shown in Figure 2 so that lies parallel with member 28, it is necessary to provide some sort of rigid support for the member and this support comprises an arm 50 having a clamping part 51 to embrace the section 28', while the inner end of the arm is supported upon the section 28 or is stationary relative .to this section.

The inner end of the arm is provided with a sleeve 52 embracing member 28 and disposed between bracket 32 and bearing 27. From this, it will be apparent that when the member 28 is moved to a position parallel with member 28, it will be securely held in this position through the clamp member 51 on arm 50.

The section 28 adjustably supports the conveyor 53, through the medium of the collars 54, embracing member 28' and movable therewith. The conveyor 53 may be any conventional type including loading buckets 54 operated through the sprocket and chain connections and has at its upper end an angularly disposed chute 55 whereby the material carried upwardly by buckets 54 will be de posited in the chute and carried ofi to the desired location.

In order to impart movement to the several parts described, the driving connection to the motor 3 will now be set forth. Mounted upon shaft 10 is a sprocket 56 operatively connected to sprocket 57 on stub shaft 58 over sprocket 62, sprocket 64 and sprocket 65, the latter on shaft 63. Sprocket 62 is 1'0- tatably mounted upon the stationary tubular member at while sprocket 64 is carried by the movable ring 66 which is connected by means of rod 67 to the upper end of the movable tube 6. Y

In order to prevent movement on the part of the ring 66 relative tomember 4, the ring 66 is provided with guide grooves, receiving the guides 68.

From this, it will be apparent that regardless of the position of the member 6 relative to the member 4., operative connection between shafts 58 and 63 is established.

Upon the outer end of shaft 63 is a sprocket 69 operatively connected with sprocket 70 upon the end of shaft 34 which imparts movement to shaft 34 and extension part 37. Shaft 34 also supports a sprocket 71 operatively connected with sprocket 7 2 upon the outer end of shaft 31, thus imparting movement to shaft 31.

lVhen it is desired to rotate the tubular parts 28 and 28, it will be noted that part 28 is connected to shaft 63 through the operation of a clutch 7 3 disposed between bevel gears 74 which co-operates with bevel gear 7 5 on stub shaft 76. The stub shaft 76 carries a sprocket 7 7 operatively connected with sprocket 78 which operates a worm 79 meshing with the worm gear 80 on member 28. From this, it will be apparent that through the medium of the clutch 7 3 rotative movement may be imparted to members 28 and 28. It will be apparent that the opposed bevel gears 74 are loosely mounted on shaft 63 and are only rotated through their connection with clutch 73.

It will be apparent from the foregoing, that upon the rotation of shaft 34 and part 37, the sprocket 81 upon the outer end of part 37 will be actuated and as it has operative connection with sprocket 82 on conveyor shaft 83, movement will be readily imparted to the conveyor.

The shaft 83 supports the spaced sprockets 84 operatively connected to similar sprockets 85 on shaft 86 thus imparting movement to the buckets 54.

On the outer end of the extension part 37 there is mounted a second sprocket 87 spaced from sprocket 81 and adapted to be opertively connected with sprocket 87 on shaft 31 when the member 28 is moved to a position parallel with member 28 as shown by dotted lines in Figure 2, so that operative connection to the conveyor may be established regardless of the position of the member 28'.

WVhile I have shown and described the preferred embodiment of my invention, it will be apparent that slight changes may be made in the construction when putting the invention into practice without departing from the spirit of the same or the scope of the appended claims.
